I Application filed January 4, 1915. Serial No. 360.

To all whom it-ma e concern: r

- Be it known that I, WILLIAM TR'nusrrEL, v a citizen of the United States, and. a. resident of Maple Valley, in the county of Kingand State of Washington, have invented. certain new and useful Improvements :in Surface-Gages, of which the following is a' full, true, and exact'specification. My invention relates to surface gages of that particular class which is adaptable-to and'has for its principal object; to provide an improved ad-. justable, direct reading indicating gage of the above general description. Other objects. will appear as my'invention is more fully explained-in the following-specification, illustratedin the accompanying drawings and pointed out in the appended claims In the drawings, of my device.v Fi-g..

Figure 1 is a bottom plan 2 is a side elevation of same shown gaging a saw, with 'parts p plan view of same. 7 Referring more particularly to the drawings, numeral 1 designatesaa framemember downwardly extending leg 2 on one end and two outstanding arms 3 which are provided with legs a similar to legs 2. Legs 2 and 4; are finished on the end to a true bearing surface. The other end ofbody 1 is cored at 5 to receive a circular disk 6 which is providedwith a'direct 'r'eading scale along the .outer edge of its lower face. The periphery of disk 6 may be milled if desired to facilitate 'being'turned'by the thumb and finger. Disk 6 has a centrally threaded hole which which passesthrough a hole in the upper portion 8 of body 1. The lower end of screw 7 is shouldered and ,squared, as at 9 and is adapted to fit into and extend through a square hole in the .bottom part 10' of body 1. A knurled thumb-nut 11 screws onto screw 7 and is adapted to lock said screw 1 and thereby the-disk 6 in any desiredposition. The extreme outer end of the body is provided with a reading opening 12 and an indicating point 13 which extends slightly beyond the edge of disk 6 and fits down dicat'e more clearly disk. 6 solidly against being gaged has the desired- .gage may be set to gage any screws onto a screw 7 closely to the face of the exact reading on.- the disk 6..

The operation of my device is Thethumb nut llis loosened and the disk 6 rotated and set to' read the desired-amount said disk so as to in-- as follows of extension of squaredpoint 9 below the lower surface of body 1. Thumb. nut 11 is screwed down until it clamps screw 7 and movements" The gage is now ready for use as shown in Fig. 2, the gage point 9 being placed upon the extreme end of the'toothto be gaged. If the gage now sets solidly on all four bearing points,

that the tooth set, but if thegage rocks on legs 4 as bearing points, it indicates that-the tooth has not enough set while if the gage rocks sidewise about leg 2 and point 9, it indicates too much namely 2, 4 and.9, it indicates set of the tooth. It will be understood that it is very desirable that all teeth of a saw have exactly the same is difficult operation. give different be used for It is desirable tosets to saws which are to different work and that my desired set of teeth.

While I have shown a particular form of embodiment of my invention, I am aware that many minor changes therein will read: ily suggest themselves to others skilled in set and that it the art, without 'dep'artingfrom the spirit and scone of the invention, and I therefore desire to avoid being limited to the'exact form shown and described, except as defined in the appended claim.

Having described my invention, what I claim as new and desire to protect by Let- ,ters Patent, is-

In an article o'f the class described, the

combination of a cored body, projections which extend from the body and which are intermediate the ends thereof, supporting legs upon the endsof the said projections and a similar leg upon one end of the body, all of the said legs being rigid with the body .and all of which project the same distance below the body, another legand means for adjusting the same with respect to the body.
